英文摘要：

This paper presents a nonlinear adaptive robust controller optimize design based on genetic algorithm for permanent magnet linear motor servo system. On the basis of the system nonlinear mathematical model,an error system dynamic equation is set up. The track and disturbance restraint are summed up to nonlinear adaptive robust control question. Furthermore,a theory including formulaes of resistance and inductance identification used to describe nonlinear adaptive robust controller is obtained by defining storage function. The nonlinear adaptive robust control law which meets disturbance restraint and asymptotical stability is proved. Finally,genetic algorithm is used to optimize parameters of nonlinear adaptive robust controller. The simulation results show the effectiveness of the designed controller.
